Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.75 Safari/537.36 Steps to reproduce the problem: 1. Disable third party cookies 2. Open a webpage with javascript enabled 3. Open the Sources tab in the developer tools What is the expected behavior? Scripts are shown in the sources tab, breakpoints can be set in the code, debugger statements set breakpoints. What went wrong? Any JS scripts are not shown in the sources panel, thus breakpoints cannot be set from the developer tools. Debugger statements are wholly ignored. Did this work before? N/A Chrome version: 55.0.2883.75 Channel: stable OS Version: Ubuntu 14.04 Flash Version: Shockwave Flash 23.0 r0 Even if this is expected behaviour and somehow not fixable due to the way the devtools interact with the page, it would probably be great to mention it somewhere or show a warning somewhere when the devtools are opened.

Unable to reproduce this issue on Ubuntu 14.04 using chrome latest stable M55-55.0.2883.75 by following steps mentioned below. 1. Disabled third party cookies from chrome://settings 2. Navigated to sample webpage which has JS code (http://www.w3schools.com/js/js_examples.asp) 3. Switched to Dev tools--> Source tab--> Set break point 4. Observed debugger statements set breakpoints as expected Benjamin@ Could you please confirm the above steps is the right way to reproduce this issue? If no, please correct us. Thanks!

I am currently also unable to reproduce. The reason I boiled the problem down to the cookies setting was because the inspector threw an error (Visible when inspecting the inspector) about being unable to access the localstorage. I'll try to reproduce again tomorrow. After blocking third party cookies just now the inspector did not show the scripts in the sources tab, but a page refresh solved that problem.

Definitely interested in what caused the tabs to break, but Yeah i doubt it was the third party cookies setting. You can look at about:version to see what other nondefault flags you have enabled. |
